Refund policy
Return & Refund Policy
Last updated: September 11, 2026
Your Statutory Rights
Nothing in this policy limits your statutory rights under applicable consumer protection laws in your jurisdiction. You are entitled to a refund or replacement for products with major manufacturing defects, misdescription, or damage during transit as required by law.
General Return Policy
For regions outside the European Union: We do not accept returns or issue refunds for change of mind, incorrect model selection, dissatisfaction with sound signature, system compatibility issues, or personal preference reasons.
Tube amplifiers are subjective audio devices. Sound perception varies by individual, speaker pairing, room acoustics, and source equipment. As long as the product matches published specifications, sound preference does not qualify as a product defect.
To be eligible for any return, your item must be in the same condition that you received it, unused, with tags, and in its original packaging. All original accessories, manuals and components must be intact. You’ll also need the receipt or proof of purchase.
To start a return, you can contact us at info@lm-audio.com. Returns will need to be sent to the following address:
Attn: Line Magnetic
Entire 5/F, Grancastle Commercial Centre
2T Sai Yeung Choi Street South
Mong Kok, Kowloon
Hong Kong
Tel: +852 2361 1229 / +852 9388 2988
If your return is accepted, we’ll send you a return shipping label, as well as instructions on how and where to send your package. Items sent back to us without first requesting a return will not be accepted.
You can always contact us for any return question at info@lm-audio.com.
Non-Returnable Items
The following items are final sale and cannot be returned for non-quality reasons:
Custom-built tube amplifiers (made-to-order units with custom transformers, tube configurations, or finishes)
Demo units, open-box items, and products marked "Final Sale"
Loose vacuum tubes, fuses, and other consumable accessories (defective units on arrival are still covered)
Products that have been disassembled, modified, or tampered with by the customer
Damaged, Defective, or Incorrect Items
Please inspect your order upon reception. If your amplifier arrives physically damaged, with manufacturing defects, or is the wrong model, please contact us at info@lm-audio.com within 14 days of delivery with:
1. Your order number
2. Clear photos of the outer packaging and the issue
3. Photos of the product serial number label
We will verify the issue and offer a resolution, which may include a full refund, replacement, or repair at our discretion. You do not need to ship the item back unless we explicitly request it.
No Fault Found Policy
If a returned unit passes our full factory testing and meets all published specifications (no fault found), the return will be classified as a change-of-mind return.
In this case, we reserve the right to reject the refund or deduct all shipping costs and a restocking fee (up to 20% of the purchase price) from the refund amount. The customer is responsible for all return shipping costs in this scenario.
Vacuum Tube Coverage
Stock tubes included with new amplifiers are fully tested and burned-in before shipping. Dead-on-arrival (DOA) tubes will be replaced free of charge.
Tubes are consumable components with a limited service life. Normal wear and tear, tube failure due to improper use, or customer-replaced tubes are not covered under this policy.
Exchanges
The fastest way to ensure you get what you want is to return the item you have, and once the return is accepted, make a separate purchase for the new item.
European Union 14 day cooling off period
Notwithstanding the above, if the merchandise is being shipped into the European Union, you have the right to cancel or return your order within 14 days, for any reason and without a justification. As above, your item must be in the same condition that you received it, unused, with tags, and in its original packaging, all accessories intact. You’ll also need the receipt or proof of purchase.
Refund Processing
We will notify you once we’ve received and inspected your return, and let you know if the refund was approved or not.
Approved refunds will be issued to your original payment method within 5-7 business days. Please note that your bank or payment provider may take additional time to process the transaction.
If more than 15 business days have passed since we’ve approved your return, please contact us at info@lm-audio.com.
